💖 rte_tm_driver.h — Library Functions Manual 💖

okay bestie, welcome to rte_tm_driver.h, a lil header from the DPDK crew 🫶 it's a Library Functions Manual page and it's giving "internals only, do not perceive me." stay with me, it's short and cute.

✨ NAME ✨

rte_tm_driver.h — literally just the header itself, that's the whole name, no notes 💅

#include 'rte_ethdev.h'
#include 'ethdev_driver.h'
#include 'rte_tm.h'

🎀 Functions 🎀

static int rte_tm_error_set (struct rte_tm_error *error, int code, enum
    rte_tm_error_type type, const void *cause, const char *message)

🦋 Detailed Description 🦋

RTE Generic Traffic Manager API (Driver Side) ✨

so like, this file hands out implementation helpers for internal use by PMDs. it is not meant to be exposed to applications, and it is not subject to ABI versioning. read that again bestie — no ABI promises here, none, zero, periodt. 🙈

👑 Function Documentation 👑

💜 int rte_tm_error_set (struct rte_tm_error * error, int code, enum rte_tm_error_type type, const void * cause, const char * message)

[inline], [static] — yes queen, both.

Initialize generic error structure. 🛠️

this function also sets rte_errno to a given value. the way it just does that, iconic.

Parameters

• error — Pointer to error structure (may be NULL). yes, NULL is allowed, no judgement 🌈
• code — Related error code (rte_errno).
• type — Cause field and error type.
• cause — Object responsible for the error. we found the culprit 🔍
• message — Human-readable error message.

Returns

Error code.

💜 const struct rte_tm_ops * rte_tm_ops_get (uint16_t port_id, struct rte_tm_error * error)

Get generic traffic manager operations structure from a port 🎀

Parameters

• port_id — The port identifier of the Ethernet device.
• error — Error details.

Returns

The traffic manager operations structure associated with port_id on success, NULL otherwise. so if you get NULL... that's a no from the port, bestie 😭

lowkey a warning for you: these helpers are internal PMD stuff, not for applications, and there's no ABI versioning protecting you. fr fr, don't build your app on them and then act surprised. 💀
